    abstract =  {The One-way Active Measurement Protocol (OWAMP) and Two-Way Active Measurement Protocol (TWAMP) security mechanisms require that both the client and server endpoints possess a shared secret. This document describes the use of keys derived from an IKEv2 security association (SA) as the shared key in O/TWAMP. If the shared key can be derived from the IKEv2 SA, O/TWAMP can support certificate-based key exchange, which would allow for more operational flexibility and efficiency. The key derivation presented in this document can also facilitate automatic key management.},
